	 <p>This appendix describes features of Intel Threading
		Building Blocks (Intel&reg; TBB) that remain for compatibility with previous
		versions. These features are deprecated and may disappear in future versions of
		Intel&reg; TBB. Some of these features are available only if the preprocessor
		symbol TBB_DEPRECATED is non-zero.
